No one likes a flickering light source, but lighting is often dependent on the quality of a building’s main AC power. Light intensity has a close relation to the supply voltage, but bulb type ...

Blinking an LED with three resistors and a capacitor. Ok, ok… one of the resistors is a light-dependent resistor, but still. In reality, this is a classic relaxation oscillator. The capacitor ...

This bulb and battery cell below are connected ... When the light sensor in this light dependent resistor (LDR) detects an increase or decrease in light, it switches the circuit on or off.
